USPS Postage Rates: How Much Does It Cost to Mail a Letter?

Quick answer
A typical letter requires one 82-cent stamp to mail.
When the Post Office raises its prices, we eventually have to raise ours too. Unfortunately, that's just the reality of running a mailing business: everything gets more expensive over time, and USPS still has an enormous network to operate. The latest increase moved a Forever Stamp from $0.78 to $0.82. Honestly, four cents is pretty reasonable for getting a letter across the country, so I don't think many people are going to lose sleep over it.

How Forever Stamps Hold Their Value
At The Letter Pilot, we print enough mail that even a small postage increase adds up. When USPS announces a new rate, we'll usually buy Forever Stamps before it takes effect so we can lock in the lower purchase price for some of our future mail.
A Forever Stamp is tied to the current price of mailing a 1-ounce First-Class Mail letter, not the price printed on a receipt when you bought it. If we paid $0.78 for a stamp and the current letter rate is $0.82, that same stamp still covers the full $0.82 postage. In practical terms, we saved four cents on that future mailing. It's not exactly an investment portfolio, but it's a pretty useful way for a mail-heavy business to stay ahead of a rate increase.
Recent Forever Stamp Prices

How Much Is a Book or Roll of Stamps in 2026?
Buying in bulk doesn't get you any discounts, but it might save you a trip to the Post Office. At $0.82 per stamp, a book of 20 costs $16.40, and a coil of 100 costs $82.00.
| Format | Stamps | Current postage value |
|---|---|---|
| Single Forever Stamp | 1 | $0.82 |

The One Business Mailing Rate Worth Knowing
Most people do not need to worry about business mailing rates. One exception is Every Door Direct Mail, usually shortened to EDDM. EDDM Retail currently costs $0.260 per piece. It is mainly useful for businesses that want to advertise to every address along selected neighborhood routes, whether that means promoting a local offer or trying to generate leads nearby.
For ordinary letters, this probably does not apply to you. EDDM uses qualifying marketing-mail flats and its own preparation rules. USPS says EDDM Retail mailings must include at least 200 pieces, with a limit of 5,000 pieces per day per ZIP Code. You can choose the neighborhoods and carrier routes through the USPS mapping tool instead of building a traditional mailing list.
